Resiliently mounted wheel assembly

ABSTRACT

a resiliently mounted wheel assembly has a tread ring, an annular member, a plurality of bearing elements for rotatably mounting the tread ring on the annular member, an elastomeric ring member resiliently supporting the annular member, and an arbor mount supporting the elastomeric ring member and being of a construction sufficient for movement of the annular member between two positions spaced a preselected axial distance apart and allowing the tread ring to self-alignably engage a surface.
